The new concept of cutting processing The nowadays cutting tool company cannot only be again the manufacture and the sales cutting tool, in order to succeed, they must be consistent with the globalization manufacture tendency maintenance, through enhances the efficiency, cooperates with the customer reduces the cost。 Approaches the instantaneous global competition after this after NAFTA, the WTO time, the world company is making quickly to the same feeling, is lighter, a cheaper response。 In other words, they make the product and the components contain can in high speed under revolve, as a result of the cost pressure, best, is lighter moreover must make cheaply。 Obtains these goals a best way is through develops and applies the new material, but these is new and the improvement material usually all with difficulty processes。 In in this kind of commercial power and the technical difficulty combination is especially prominent in the automobile and the aviation industry, and has become has the experience the cutting tool company to research and develop the department the most important driving influence。82695

For example, takes the modular cast iron to say that, it has become the engine part and other automobiles, the agriculture the material which see day by day with the equipment and in the machine tool industry components。 This kind of alloy provides the low production cost and the good machine capability combination。 They are cheaper than the steel products, but has a higher intensity and toughness compared to the cast iron。 But at the same time the modular cast iron is extremely wear-resisting, has fast breaks by rubbing the cutting tool material the tendency。 In this wear resistant very great degree bead luminous body content influence。 Some known modular cast iron bead luminous body content higher, its resistance to wear better, moreover its machinability is worse。 Moreover, the modular cast iron porosity causes off and on to cut, this even more reduces the life。 

May estimate that, the high degree of hardness and the high wear-resisting cutting material quality must consider the modular cast iron the high resistance to wear。 And the material quality contains extremely hard TiC in fact (carbonized titanium) or TiCN (carbon titanium nitrides) thick coating when cutting speed each minute 300 meters processes the modular cast iron to prove usually is effective。 But along with cutting speed increase, scrap/The cutting tool junction plane temperature also is increasing。 When has such situation, the TiC coating favors in has the chemical reaction with the iron and softens, more pressures function in anti- crescent moon hollow attrition coating。 Under these conditions, hoped has one chemical stability better coating, like Al2O3 (although under low speed was inferior to TiC hard or is wear-resisting)。 

The chemical stability becomes an important performance performance piding line compared to the resistance to wear the factor, the speed and the temperature is decided in is processed the modular cast iron the crystal grain structure and the performance。 But usually thick coating of TiCN and TiC or only ductile iron oxides in the soil coating is applied to, because the today majority of this kinds are processed the material the cutting speed in each minute 150 to 335 meters between。 Is higher than each minute 300 meter applications regarding the speed, the people to this kind of material are satisfied。 

In order to cause this scope performance to be  most superior, the mountain high researched and developed and has promoted in view of modular cast iron processing material quality TX150。 This kind of material quality has hard also the anti- distortion substrate, is very ideal regarding the processing modular cast iron。 Its coating the oxide compound coating which hollowly wears by thick very wear-resisting carbon titanium nitrides and a thin anti- crescent moon, the top is thin layer TiN。 This kind of coating which needs the center warm chemistry gas phase deposition using the state of the art production resistance to wear and the anti- crescent moon hollow attrition which the CVD coating complete degree of hardness moreover the tough smoothness increases (MTCVD) the craft。 Substrate/The coating combination performance gives the very high anti- plastic deformation and the cutting edge micro collapses the ability, causes it to become under the normal speed to process the modular cast iron the ideal material quality。
